Sandy Ryza commented on SPARK-1675:
-----------------------------------
I think it still wouldn't hurt to add a remark that input data doesn't need to
be centered. Should have marked this trivial when I filed it - not a big deal
either way.
> Make clear whether computePrincipalComponents requires centered data
